Rules is rules. She knew them.
What , even if she was young and foolish when she had it done in the days when she thought she was going to be a disc jockey or something?
Wonder if we would also turn away anyone who because of their native homeland tradition of scoring the skin into raised patterns on the face ,now had decorative scarring showing?
Its not like she would be front of desk at an office or shop, where she might put customers in the wrong frame of mind, is it.Under those circumstances it should definitely be left to the judgement of the owners I think.
I think it would be better if she was allowed in , subject to all other normal checks, but then told because of the rules, she would have to use concealer whenever she was in formal military dress. Could that work?
She could then make her own choice as to what was most important to her . That in itself could be quite revealing I think as to her suitability .
